Docker - free up space after removing all images & containers [closed]
For my current docker version (1.12.1 for both Client & Server) a way to delete all volumes is by using:
docker volume rm $(docker volume ls -q)
but the following is safer: (thanks Matt for your comment)
$(docker volume ls -qf dangling=true)
Also from version: 1.13.0 (2017-01-18) some commands were added:
$ docker system prune$ docker container prune$ docker image prune$ docker volume prune$ docker network prune
Changelog: Add new
docker system
command withdf
andprune
subcommands for system resource management, as well asdocker {container,image,volume,network} prune
subcommands #26108 #27525 / #27525
Most of the space is occupied by docker volume
as you can see from your output:
12G ./volumes
Docker volumes are used to persist data for docker container and to share data between containers, and they are independent of the container’s lifecycle. So removing image/container will not free the disk space they occupied. Please refer to their official docs for more details.
If you're using latest version of docker, you can find volume related commands docs for more details(list/remove/create volumes e.g), for older version of docker, you can refer to this script on github for how to clean up volumes.
Hope this could be helpful:-)
